STORE-SERVICE APPARATUS.

Specification of Letters Patent.

Patented Sept. 26, 1916.

Application filed June 10, 1916. Serial No. 102,880.

T 0 all whom it may concern:

Be it known that I, ISADORE SHEFFER, a citizen of the United States, residing at Jackson, in the county of Madison and State of Tennessee, have invented or discovered certain new and useful Improvements in Store-Service Apparatus, of which the following is a specification, reference being had therein to the accompanying drawing.

In store service systems now in use, and comprising overhead wire tracks on which the carriers run by gravity, it is necessary for the wire tracks to be kept clean or free from dust or rust, in order that the carriers may run thereon easily and properly.

This invention has for its object'to provide simple means whereby the wire tracks may always be kept clean so that the carriers will run freely thereon. To this end, in carrying out the invention, the traveling carriers or trolleys running on the wires are provided with wipers preferably pressing yieldingly against the wires and preferably having absorbent contact faces so that they may apply a lubricant to the wires when passing over the same, all as will hereinafter more fully appear.

In the accompanying drawing Figure 1 shows a part of a well-known form of store service apparatus with my invention applied thereto. Fig. 2 illustrates a portion of the same on a somewhat larger scale than Fig. 1. Fig. 3 shows a different form of carrier or trolley from that illustrated in Figs. 1 and 2, with my invention applied thereto. Fig. 4c is a detail perspective view of a preferred form of the invention.

Referring to the drawing, 12 denotes a wire track on which a carrier 13, provided with a trolley wheel or wheels 14, is adapted to run, and from which a receptacle or basket 15 is suspended. Suitably mounted with reference to the carrier 13 are wipers 16 contacting with the wire track 12, so that as the carrier passes along said track the wipers will remove dust or dirt therefrom and keep the same clean and bright. These wipers 16 consist preferably of blocks of any suitable material and preferably having contact faces 17 of felt or other suitable soft material sufficiently absorbent to hold a small amount of oil to be supplied to the track and thus keep the same slightly greased so that it will not rust; or if there should be any dirt or rust on the track the same will be removed by the wipers passing over it. The wiper blocks 16 may, if desired, be provided with holes or pockets 16 to hold a small amount of oil.

The wipers 16 are preferably jointed to the lower ends of links 18 hinged at their upper ends to brackets 19 attached to the carriers 13. For the purpose of yieldingly pressing the wipers against the wire track 12 springs 20, arranged to press downward on the links 18, are preferably provided.

From the foregoing it will be understood that the tracks of store service systems on which carriers or trolleys provided with the present invention run will be kept free from dust or rust, so that the carriers or trolleys will, at all times, run freely thereon.

Having thus described my invention I claim and desire to secure by Letters Patent:

1. In a store service apparatus, a carrier adapted to run on a track, said carrier being provided with one or more wipers contacting with said track and serving to keep the same clean as the carrier passes along the track, said wiper or wipers being faced with absorbent material adapted to hold a lubricant.

2. In a store service apparatus, a carrier adapted to run on a track, said carrier being provided with one or more spring-pressed wipers contacting with said track and serving to keep the same clean as the carrier passes along the track, said wiper or wipers being faced with absorbent material adapted to hold a lubricant.

3. In a store service apparatus, the combination with a carrier adapted to run on a track, said carrier being provided with brackets, of spring-pressed links hinged at their upper ends to said brackets, and wipers jointed to the lower ends of said links and adapted to press against the track on which the carrier runs, said wipers being faced with absorbent material adapted to hold a lubricant and thus clean and oil the track.
